Adapting a 7 pin vehicle connector to a 9 pin Airstream connector

We have a 7 pin connector on our 2005 Yukon and a 9 pin on our 1985 Airstream Safari. Is their an adapter that can be purchased to go from the 7 to 9 or do I have to make one?

You might find one, but the 9 pin was only used for a few years and are not very common. It might be easier to just rewire the truck end with a 7 pin plug.

I agree with Richard. I looked for an adaptor and couldn't find one online. it would be easier just to take the 9 pin of and put on a 7 pin...

May you have at least one sunny day, and a soft chair to sit in..

Thank you both!!

My dilemma is that I am traveling from Jacksonville, FL to Henderson, NC to pick up the trailer. I'm hoping to hitch it up, tow it about 7 miles to have new tires put on, brakes checked and bearings repacked then head back to FL. I won't have the tools or the time to re-wire the trailer in Henderson. What I think I will do is buy the 7 pin male connector with pigtail and the 9 pin connector (wife found them on the internet), take my voltmeter, Richard's great drawings, and a means to connect the pigtail to the 9 pin and give it a try. If that doesn't work, it could be a long day (week!?) camped at my cousins house. Back at the house I think I can do a better job of a weatherproof splice of the 7 pin into the trailer.

Reading the posts about open grounds, etc. I can't wait to troubleshoot a trailer that is new to me and has been sitting in storage over the winter. Electrons have never respected me and they are not about to start now.

Any suggestions about that?
